i'm going to be going to samara beach in costa rica in june for some spearfishing and other recreation. After many years of free diving in the bahamas with a hawaiian sling i'm ready for a change. Any advice on locations, charters, conditions(visibilty, temp., jellyfish) depths, recommended size gun, types of fish or anything else would be greatly appreciated. I'd also like input on blue water vs reef and shore dives.
